Description

Automatic sampling device and sampling bottle used for it

The present invention relates to an auto sampler, and more particularly, when taking a sample to analyze the state of a chemical solution (chemical solution), several types of samples can be collected from one sampler, thereby maximizing efficiency, as well as The lid is automatically removed during sampling and the container for sample collection is automatically reversed so that the lid and container are washed with ultrapure water or undiluted solution before use. Improved auto to minimize contamination of chemical solution from contaminants attached to containers or lids, but to enable sampling from multiple liquid chemical sources using one device through optimal design It's about the sampler.

In general, chemical solutions used in various industrial fields as well as semiconductor manufacturing processes are subjected to analysis operations such as concentrations and components after taking samples to confirm characteristics.

In this case, the sampling operation is performed by taking a chemical solution sample into a container.

Usually, the washing water or the chemical solution to be sampled is put into the container before collection, the lid is closed and the washing is performed by shaking, and then the washing solution is discarded and the chemical solution sample to be sampled is placed in the container.

At this time, if the chemical solution is sampled without cleaning the container, the accurate analysis becomes difficult due to contamination by the substances (including components) remaining in the container, thereby reducing the reliability of the sampling analysis.

Residual contaminants can be many, including particles as well as organic carbon, oils, insolubles, and other unwanted substances.

For this reason, it is desirable that the container and lid containing the sample be cleaned immediately prior to sampling.

On the other hand, as described above, in the conventional container cleaning method, problems such as the need for manpower and non-homogeneity of cleaning quality are expected because the operator had to manually hold the sample container by hand.

In addition, if the residual material remaining in the container to be sampled is toxic or fatal to the human body, it is very vulnerable to safety accidents because the residual material may splash or bury on the body such as the operator's hand during sampling operation, causing personal injury. did.

Accordingly, the present applicant has developed Patent Application No. 10-2018-0102784 (2018.08.30.) 'Auto Sampler'.

The technology developed by the present applicant is to increase cleaning efficiency and prevent safety accidents by automatically inverting and cleaning the sampling container.

However, the development technology of the present applicant is a semi-automated intermediate development stage for full automation, and has a limitation in that the operator has to manually operate the arm while wearing the glove to separate the lid from the container.

Therefore, the present invention is a time when it is necessary to take a technological leap forward to a Full Auto Sampling System that fully automates even this process.

Furthermore, there is a need to design the volume of the equipment to an optimal size so that it can be efficiently and effectively processed without occupying a lot of space during installation.

Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

Prior to the description of the present invention, the following specific structural or functional descriptions are only exemplified for the purpose of describing embodiments according to the concept of the present invention.

Accordingly, embodiments according to the concept of the present invention may be implemented in various forms, and should not be construed as being limited to the embodiments described herein.

As shown in FIG. 1 , the auto sampler according to the present invention includes a lower housing 100 having a rectangular parallelepiped shape.

In addition, the base plate 110 is fixed to the upper end of the lower housing 100 , and the upper housing 120 forming a space therein is seated and fixed on the upper surface of the base plate 110 to seal the inside.

In addition, the inner space of the upper housing 120 is divided vertically by the transverse partition wall 130 , and the lower space is further divided into left and right spaces by the vertical partition wall 140 .

At this time, the upper space partitioned by the transverse bulkhead 130 forms a machine room (ROOM), and among the lower spaces partitioned by the longitudinal bulkhead 140, the left space is the vessel waiting chamber 200, and the right space is the sampling chamber ( 300) is formed.

In addition, a part of the longitudinal partition wall 140 dividing between the container waiting chamber 200 and the sampling chamber 300 is opened so that both chambers 200 and 300 can be communicated, and the open part is opened and closed in the vertical direction. A door (DR) for sealing possible is installed.

Then, the space in which the container BT to contain the sample solution is prepared and the container waiting chamber 200 is spaced apart from the base plate 110 by a predetermined height so that the container BT can be prepared in the standby state. A rotatable container rotating plate 210 is installed.

At this time, as shown in the example of FIG. 3, the container rotation plate 210 has a plurality of container insertion grooves 212 having one side open at regular intervals along the circumferential direction.

In addition, in the container waiting chamber 200, on the outside of the concentric circle of the container rotation plate 210, the container departure prevention guide plate formed in a circular shape inside at the same level with the container rotation plate and the container in between is formed in the area except for the door section. There is a container rotating plate 210 to prevent the container from being separated when rotating.

Therefore, when the open portion of the container insertion groove 212 is rotated upwards at the center of the door DR, the container BT trapped in the container insertion groove 212 is taken out when the door DR is opened. can do.

That is, the opened portion of the container insertion groove 212 is the side adjacent to the door DR described above. This is because the container BT must be able to be taken out when the door DR is opened.

In addition, the lower end of the rotating plate rotating shaft 220 is fixed to the center of the circle of the vessel rotating plate 210 .

And, the upper end of the rotating plate rotating shaft 220 is exposed to the machine room (ROOM) through the transverse bulkhead (130).

In addition, it is coupled to the motor rotating shaft of the rotating plate driving motor 230 in the machine room (ROOM) and configured to rotate the container rotating plate 210 by a predetermined angle according to the rotational driving of the rotating plate driving motor 230 .

In particular, as illustrated in FIG. 3 , a swing motor 250 is further installed adjacent to the rotary plate driving motor 230 , and a switch arm 252 is connected and fixed to the motor shaft of the swing motor 250 .

At this time, the swing arm 252 is formed in a 'L' shape, penetrates vertically through the transverse bulkhead 130 and is disposed below the swing arm 252 .

In addition, a sliding guide 260 having a guide groove 262 in a straight line toward the sealing door DR is fixed to a lower portion of the swing arm 252 .

In addition, one end of the sliding guide 260 may be fixed on a guide frame (not shown) to which the sealing door DR is assembled.

In more detail, as shown in an enlarged view in FIG. 3 , the upper end of the forward and backward arms 270 is assembled to the sliding guide 260 in a dovetail shape, so that the forward and backward arms 270 smoothly do not depart from the sliding guide 260 . It is configured to be able to move forward and backward.

This is because the LM bearing type accompanied by oil cannot be used in the container and atmospheric chamber 200 requiring cleanliness, so a dovetail type assembly structure is introduced to solve this problem.

In addition, the upper end of the 'L' shape of the forward and backward advancing arms 270 is linked to the guide groove 262 of the sliding guide 260 .

In addition, at least one known vacuum suction plate is installed on the lower front surface of the forward and backward advancing arms 270 to hold the container BT by vacuum suction.

Here, a long hole is formed at the end of the swing arm 252 so that the forward and backward arm 270 can smoothly move along the guide groove 262 of the sliding guide 260 when the swing arm 252 rotates.

And, the pin of the upper end of the forward and backward advancing arms 270 on the long hole is linked.

In addition, it is better if a detection sensor 272 is further installed on one side of the lower end of the forward and backward advancing arm 270 so that it can be detected in advance whether there is a container BT in the front.

In this case, the detection sensor 272 is not particularly limited, but may be a proximity sensor.

On the other hand, the sealing door (DR), as shown in Figures 2 to 4, both upper ends are each bound to the door lifting rod (242).

In addition, each of the door lifting rods 242 is assembled to the door lifting cylinder 240 and configured to ascend or descend according to the lifting operation of the door lifting cylinder 240 .

That is, when it rises, the container waiting chamber 200 and the sampling chamber 300 communicate with each other, and when it descends, the container waiting chamber 200 and the sampling chamber 300 are completely isolated from each other.

This is to prevent the spread of scattering liquid or fumes from the sampling chamber 300 toward the container atmosphere chamber 200 because it deals with chemicals that are dangerous substances.

In addition, the door lifting cylinder 240 is firmly fixed on the transverse bulkhead 130 .

In addition, as shown in FIGS. 2 and 4 to 7 , the sampling chamber 300 is provided with a lid gripper 310 .

In addition, the lid gripper 310 is fixed to the end of the gripper fixing tube 320 .

In addition, the upper end of the gripper fixing tube 320 is fixed to the bearing on the fixing plate 330 so that it can be rotated in place through the transverse bulkhead 130 that separates and partitions the sampling chamber 300 and the machine room (ROOM).

At this time, the gripper operation cylinder 340 is fixed to the upper end of the gripper fixing tube 320 .

In addition, the gripper operation rod 342 connected to the gripper action cylinder 340 penetrates the gripper fixing tube 320 up and down and is connected to the lid gripper 310 .

That is, the gripper fixing tube 320 has a rotatable structure and the gripper operation rod 342 installed through the inside is configured to be movable up and down according to the operation of the gripper operation cylinder 340 . do.

This is necessary because, when the lid CAP is opened, the lid CAP can be opened only when the lid CAP rises from the container BT by the amount of rise due to screw sliding.

In addition, the lid gripper 310 includes a fixed body 312 that has a divided structure and is fixed to the gripper fixture tube 320 in a form surrounding the gripper fixture tube 320 .

In addition, a vertical flow block 314 is provided inside the fixed body 312 . The vertical flow block 314 is fixed to the end of the gripper operation rod 342 inserted through the gripper fixing tube 320 . In addition, the vertical flow block 314 is formed with inclined grooves INC on both sides.

Then, the left and right flow blocks 316 are assembled in the inclined groove INC, and the left and right flow blocks 316 slide in the inclined direction.

In addition, a grip portion 318 is formed at the lower end of the left and right flow block 316 , and the grip portion 318 has a curvature, and irregularities are formed on the inner circumferential surface where the curvature is formed.

At this time, the portion symmetrical in the radial direction of the fixed body 312 should be opened so that the left and right flow blocks 316 can protrude and retract.

Thus, when the gripper action cylinder 340 operates to lower the gripper action rod 342 , the gripper fixing tube 320 is relatively fixed, so the fixed body 312 fixed thereto also maintains a fixed state.

Therefore, as the vertical flow block 314 fixed to the lower end of the gripping operation rod 342 descends, the left and right flow blocks 316 engaged with it at an incline are naturally pushed out and opened.

In this case, it refers to when the gripped lid CAP is released. On the contrary, when the gripping operation rod 342 rises, the left and right flow block 316 retracts, thereby gripping the lid CAP.

On the other hand, the driven gear 322 is integrally fixed to the upper end of the gripper fixing tube 320 , that is, directly below the fixing plate 330 .

And, the driving gear 352 is gear-coupled to the driven gear 322 .

In addition, the driving gear 352 is coupled to a motor shaft of the fixed tube drive motor 350 , and the fixed tube drive motor 350 is fixed to the fixed plate 330 .

In addition, the cable guide (CG) is connected to one side of the fixing plate 330 to have a flexible moving structure so that power can be continuously supplied without being cut off when the fixing plate 330 is raised or lowered.

In addition, the fixing plate 330 is installed such that one end is vertically fixed to the lower end surface of the vertical plate 360 , and the other end of the fixing plate 330 is connected to the cable guide CG, as shown in FIGS. 5 to 7 . do.

In addition, the slider 370 is fixed to one side of the rear surface of the vertical plate 360 .

At this time, the slider 370 is fitted to the LM guide 380 and is configured to be slidable in the vertical direction along it.

In addition, the LM guide 380 is vertically fixed to the upper surface of the transverse bulkhead 130 .

Here, FIGS. 6 and 7 are illustrated while omitting some of the configurations of FIG. 5 for convenience of description.

That is, the LM guide 380 is firmly fixed to one side of the plate surface of the support plate 400 , and the support plate 400 is firmly fixed by a pair of triangular support 410 to maintain a vertical state, and these support plates 400 ) and the lower end of the triangular support 410 are fixed to the upper surface of the transverse bulkhead 130 .

In addition, the shaft block 420 is installed in the space between the vertical plate 360 and the support plate 400 as shown in FIGS. 5 and 7 .

In addition, the ball screw 430 is installed to the shaft block 420 to rotate in place, the flow block 440 is toothed to the ball screw 430 , and the flow block 440 is the vertical plate 360 . ) is fixed to

Of course, the shaft block 420 is fixed to one side of the support plate 420 .

And, as shown in FIG. 5 , a driven pulley 432 is fixed to the upper end of the ball screw 430 supported to be rotated through the shaft block 420 .

In addition, a screw driving motor 450 is fixed to the other side of the support plate 420 to face the shaft block 420 .

In addition, a driving pulley 452 is fixed to the motor shaft of the screw driving motor 450 , and the driven pulley 432 and the driving pulley 452 are connected so as to transmit power by a belt 460 , the belt 460, it is preferable to use a timing belt so that the control can be performed accurately.

Accordingly, as the screw drive motor 450 rotates, the driven pulley 432 receives power and rotates to rotate the ball screw 430 fixed to the driven pulley 432, and the flow block toothed thereto. (440) is ascending and descending.

At this time, the flow block 440 is fixed to the vertical plate 360, and since the slider 370 is fixed to the vertical plate 360, the vertical plate 360 eventually ascends and descends on the LM guide 380. .

This is a structure for implementing a function that allows the lid (CAP) to be opened and lifted and then lowered or lowered (CAP) gripped and then lifted and locked again.

On the other hand, as shown in FIGS. 2 and 4 , the rotation motor 500 is further fixed on the transverse bulkhead 130 at a position directly above the sampling chamber 300 .

And, the rotational force of the rotation motor 500 is transmitted to the rotation tube 510 by the power transmission means of the pulley-belt, so that the rotation tube 510 can be rotated.

At this time, the upper end of the rotating tube 510 is rotatably fixed on the transverse bulkhead 130 by the support bearing 512 , and the lower end is fixed by being inserted into the rotating block 520 .

Accordingly, when the rotation tube 510 rotates, the rotation block 520 also rotates.

In addition, the suction block 530 is vertically installed on the rotation block 520 , and a block rod 532 is integrally fixed to the center of the rear surface of the absorption block 530 , and the block rod 532 is rotated It is assembled rotatably through the block 520 .

In particular, a pulley portion (not shown) is formed on a portion of the block rod 532 .

A rod driving belt 540 is wound around the pulley, and the rod driving belt 540 is disposed in the rotating tube 510 .

In addition, it is provided to be able to rotate in the belt guide 550 fixed on the transverse bulkhead 130 which is a position directly above the rotation tube 510 .

In addition, as shown in an enlarged view in FIG. 2 , a belt elevating cylinder 560 is further installed at the upper end of the rear surface of the belt guide 550 .

In addition, the lifting cylinder rod 562 that is drawn in and out according to the driving of the belt lifting cylinder 560 is bound to the rod driving belt 540 .

Accordingly, when the lifting cylinder rod 562 is lowered by a predetermined distance, the rod driving belt 540 descends, so that the pulley part is rotated to rotate the suction block 530 in place by the rotation amount.

Therefore, by reflecting the design value, the suction block 530 may be designed to have a stroke that can be inverted by 180°.

In addition, although not shown in the adsorption block 530, at least one known vacuum adsorption plate is installed so as to be able to hold the container BT by adsorption.

In addition, the adsorption block 530 is provided with a level sensor 534 which is a liquid level detection sensor as shown in the example of FIG. 4 .

The level sensor 534 detects when the sample solution contained in the container BT reaches a predetermined level and stops the injection of the sample solution, thereby preventing the sample solution from overflowing.

Furthermore, in the base plate 110, the spray cleaning liquid discharged from the cleaning nozzle in a state in which the opening of the lid CAP of the container BT is inverted by 180° is sprayed upwardly into the bottle, and a drain opening to drain it ( DN) is formed.

In addition, a plurality of sample inlet pipes (SP) are installed on the bottom surface of the transverse bulkhead 130 , that is, on the ceiling surface of the sampling chamber 300 .

This is arranged at a predetermined interval directly above the drain opening DN, and through this, various types of samples can be sampled through one sample device.

The present invention having such a configuration is sampled through the following operating relationship.

For example, as in FIG. 9 , first, container loading is processed in the order of bottle loading → container adsorption holding → door opening → sampling chamber recovery position.

That is, the container loading is a process of loading the container (BT) to receive the sample into the container insertion groove 212 of the container rotation plate 210, and while rotating the container rotation plate 210, the container is positioned as much as the required quantity.

At this time, the detection sensor 272 can check whether the container BT is adsorbed to the suction plate of the lower front side of the forward and backward arm 270 .

Here, the container adsorption grip is a process in which the forward and backward advancing arms 270 adsorb and hold the container BT in a vacuum adsorption method.

In addition, the door opening operates the door elevating cylinder 240 to raise and open the sealing door DR so that the container waiting chamber 200 and the sampling chamber 300 are opened to each other so that the container BT can pass. It is a process.

In this state, a container loading process is performed in which the forward and backward advancing arms 270 advance the vacuum suction and hold the container BT, and push the container BT into the sampling chamber 300 to charge the container BT.

When the container BT is charged into the sampling chamber 300, a container adsorption process in which the adsorption block 540 adsorbs and fixes the container BT is performed as shown in FIG.

And, when the forward and backward arm 270 moves backward, the sealing door DR descends to isolate between the container waiting chamber 200 and the sampling chamber 300 .

In addition, when the sealing door DR is closed and the sampling chamber 300 is sealed, the lid gripper 310 descends to grip the lid CAP.

In addition, when gripping of the lid (CAP) is completed, a lid opening process of separating and raising the lid (CAP) from the container (BT) is performed.

Then, when the lid opening is completed, the container BT adsorbed to the adsorption block 540 is moved to a desired sampling position among a plurality of sample positions by rotating the rotation block 520 .

In addition, the lid CAP is lowered to stand by at the cleaning position.

Here, before the start of rotation, the container (BT) is not in the desired sample position, that is, before sampling, the new liquid is passed through the sample inlet tube (SP) where the old liquid remains and is poured into the drain. It is necessary to completely replace the

Alternatively, after the container (BT) reaches the desired sampling position, the new liquid is discharged to the bottom and placed in the container (BT), and then the container (BT) is inverted 180° to empty the liquid in the sample inlet pipe (SP). there will also be

In addition, after inverting the container BT at each sampling position, it is also possible to clean the inside of the container BT by shooting ultrapure water or sample stock solution from the bottom upward.

At this time, the cleaning operation of the lid (CAP) may be performed by spraying ultrapure water or sample stock solution upward from the bottom of the lid (CAP) at the same time as cleaning the container (BT).

As Then, the example of Figure 11, the adsorption vessel in the sampling chamber → sample injection line sinaek passing washing → tukkeong open → pivoting movement to sample the position → reverse and the cleaning vessel and the cleaning cap → inverted and a sampling → rotated recovery position Return → Lid lock → Sampling is completed through the process of opening the door and returning to the home position.

Since this process is in the reverse order of sampling, there is no singularity.

By doing so, there is an advantage in that samples from one or several different stock solutions can be sampled using a single sample device.

On the other hand, in the present invention, as in the examples of FIGS. 12 and 13 , the sampling vessel BT is improved so that the information on the sample contained in the vessel BT can be known. .

To this end, in the present invention, a predetermined depth installation groove 610 is formed in the upper surface of the lid CAP sealing the opening of the container BT, and the installation groove 610 has an RFID (Radio-Frequency Identification) tag ( 620) is buried.

And, the installation groove 610 is sealed by the protective cover (630).

At this time, when the RFID 620 tag in the chip form is attached to the application target and the tag is operated (rotated) to reach a distance within the sphere of influence of the antenna (not shown), information is wirelessly inputted to the tag through the antenna (WRITING) can do.

In addition, after collecting the container BT and the lid CAP, the input information can be read by a method of recognizing the information through a separate reader from the outside.

In the present invention, the RFID tag 620 is embedded in the lid CAP of the container BT so that the container BT and the lid CAP of the container BT are placed within the container waiting chamber 200 at the distance of influence of the antenna. Stop the rotation within the period and record the necessary sample information.

In addition, after sampling, the container (BT) and the lid (CAP) of the container (BT) are collected and read with a reader. A number of necessary information related to the sample, such as the type of chemical contained in the container (BT), when it was sampled, etc. can be heard

In this case, a separate sealing housing 640 may be provided as shown in the example of FIG. 13 to stably fix the RFID tag 620, to be accurately positioned at a specific position, and to safely maintain the sealed state, and the RFID ( After putting 620), it can be made into a single product by sealing it with a sealing cover 650 .

In particular, when sealing the sealing cover 650 to the sealing housing 640, the projection and the groove portion can be fused by excitation with ultrasonic waves in a state in which they are engaged in a concave-convex manner to increase the sealing force.

Since these protrusions and grooves have mechanical structural features that increase the welding performance during ultrasonic welding, the sealing housing 640 and the sealing cover 650 may be engaged and fixed by ultrasonic welding in this way.

The RFID assembly formed by fusion bonding the sealing housing 640 and the sealing cover 650 to embed the RFID tag 620 is embedded in the installation groove 610 .

In this case, the welding of the sealing housing 640 and the sealing cover 650 is not necessarily limited to ultrasonic welding, and various sealing methods may be applied.

In particular, as shown in FIG. 14 , an inclined surface portion 652 is formed around the sealing cover 650 .
